System and method for facsimile load balancing

ABSTRACT

A user interface simplifies operation of a intelligent facsimile machine (IFAX). A display screen displays a plurality of menus and allows the user to select from the menus. The IFAX can store a plurality of digital cover pages to minimize transmission time for a facsimile cover page. The user may select from a list of stored digital cover pages. The user may also attach a binary data file to a facsimile message and transfer the data to another facsimile machine. The IFAX uses a storage location for storing outgoing facsimile messages. The IFAX periodically check the storage location to determine if more than one facsimile message is to be transmitted to the same location and transmits the facsimile messages in one facsimile telephone call. If the IFAX is coupled to a second IFAX on a network, the two IFAX machines can balance the work load by sending a load transfer request if the number of outgoing facsimile messages exceeds a predetermined threshold level. The IFAX can also route incoming facsimile messages to a variety of destinations such as a floppy disk or other storage device, or an external computer. The IFAX can also relay incoming facsimile messages to another facsimile machine, using a set or relay instructions. The relay instructions may be stored in the IFAX or may be a portion of the incoming facsimile message. The relay instructions may be nested, and the IFAX sends the facsimile message to a second IFAX with instructions for the second IFAX to relay the facsimile message to a third facsimile machine. The IFAX contains security measures to prevent unauthorized relaying.

CROSS-REFERENCE TO RELATED APPLICATION

This application is a division of U.S. patent application Ser. No. 08/073,511, filed Jun. 7, 1993.

TECHNICAL FIELD

This application relates generally to a user interface for an intelligent facsimile machine (IFAX) and, more specifically, to a system and method for controlling user interaction with the IFAX.

BACKGROUND OF THE INVENTION

The modern workplace has become increasingly dependent on electronic devices. Machines such as photocopiers, computers, modems, and facsimiles are now considered essential tools for the office. Many of these tools are extremely sophisticated, which can make them difficult to use. The increased capability of these tools has often outpaced the ability of the average user to efficiently operate them.

For example, an old style facsimile (FAX) machine had few options and was relatively easy to operate. Early FAX machines used an acoustical modem to couple the FAX signal to a standard telephone handset. The person sending a facsimile message simply dialed the FAX telephone number of the recipient and plugged the telephone handset into the acoustical modem when they heard an audible tone generated by the recipient's FAX machine over the handset. The FAX machine was easy to use, but had few or no options.

More modern IFAX machines have direct telephone lines as well as a long list of sophisticated options. For example, the user can elect to send a facsimile message immediately, or delay transmission to a later time at which it is automatically sent, such as at nighttime when the telephone rates decrease. The facsimile message is read by the IFAX and a digital image of the message is stored in memory within the IFAX until the designated transmission time.

With another option, the user may elect to send a facsimile message to a group of recipients that can be specified by a group identifier. The IFAX stores a list of facsimile telephone numbers, sometimes called addresses, and can be programmed to recognize various groups. The user need only provide the IFAX with the instruction to send a facsimile message to a group, such as "Sales Managers", for example, and the IFAX will automatically send the facsimile message to each facsimile telephone number associated with the group of sales managers.

Numerous other features such as speed dialing, automatic redialing, confidential facsimile transmission and reception, facsimile forwarding, facsimile relaying and facsimile polling are now available on modern IFAXs.

One problem with the advanced technological features of the modern IFAX is that they are difficult for the average user utilize without extensive training. Further, once learned, if a new IFAX is purchased, the user may have to be retrained to efficiently utilize the same features on the new IFAX.

Therefore, it can be appreciated that there is a significant need for a system and method of facsimile communication that allows a user to easily interact with the IFAX without extensive training.

SUMMARY OF THE INVENTION

The present invention is embodied in an intelligence facsimile machine (IFAX) having a display and a user input device for transmitting a facsimile cover page comprising the steps of maintaining a stored set of cover pages containing a plurality of different possible cover pages to be transmitted as a cover page to the facsimile message. The IFAX displays on the display a list of the set of stored cover pages and senses a user input on a user input device to select a particular one of the stored set of cover pages from the list. The facsimile selects the particular cover page in response to the user input and transmits the particular cover page before transmitting the facsimile message.

The method may further include the steps of storing a user created cover page as one of the set of stored cover pages and adding the user created cover page to the list of cover pages.

In an alternative embodiment, the IFAX containing a user input device is used for defining a personal facsimile cover page and maintains a stored set of cover pages containing a plurality of different cover pages. The IFAX senses the user input on the user input device to select a particular stored cover pages for use by a particular individual. In response, the IFAX selects the selected cover page and uses it as personal cover page for that individual. The IFAX may store a user created cover page as one of the stored set of cover pages and add the stored user created cover page to the list of cover pages.

In another alternative embodiment, an IFAX is coupled to a communications link and stores a binary data file in a storage location within the IFAX. A facsimile telephone number for a second IFAX is entered into the IFAX. The IFAX associates the binary data file with the facsimile message and transmits the facsimile message and the binary data file to the second IFAX over the communication link such that the binary data file is transmitted to the second IFAX as a portion of the facsimile message.

In an alternative embodiment, the IFAX has a storage location for storing facsimile messages and determines a first facsimile telephone number to which a facsimile message will be sent. The IFAX stores the facsimile message in the storage location for later transmission to the first facsimile telephone number. The storage location also contains at least one other stored facsimile message with a second facsimile telephone number to which the other facsimile message is to be sent. The IFAX compares the storage location to determine if the first facsimile telephone number matches with the second facsimile telephone number indicating that the stored facsimile message and the other stored facsimile message are both to be transmitted to the first facsimile telephone number. If the first and second facsimile telephone numbers match, the IFAX transmits the stored facsimile message and the other stored facsimile message to the first facsimile number during a single facsimile telehpone call.

In an alternative embodiment, the first and second IFAXs are coupled together to form a network. The first IFAX has a quantity of stored data files awaiting transmission and determines a value indicative of the quantity of stored data files. If the value exceeds a predetermined value, the first IFAX transfers at least one stored data file to the second IFAX over the network so that the transferred data file is transmitted by the second IFAX. The method may include the further step of determining the value after the transfer of the stored data file. The first IFAX may continue to transfer stored data files to the second IFAX until the value does not exceed the predetermined value.

In another alternative embodiment, the IFAX has a user input device and display and is coupled to a communication link and maintains a storage location containing a set of routing instructions. The routing instructions specify the manner in which an incoming facsimile message received over the communication link will be processed by the IFAX. The IFAX receives the incoming facsimile message from the second IFAX and routes the incoming facsimile message according to the routing instructions. A plurality of incoming facsimile messages may be routed according to the routing instructions.

The method may include the further steps of sensing user input to modify the routing instructions and the incoming facsimile messages will be routed according to the modified routing instructions. The facsimile messages may be routed to a personal computer, a storage device coupled to the first IFAX, or to a third IFAX.

The routing instructions may also include determining if an incoming facsimile message is capable of being stored in an in box storage location within a IFAX. If the incoming facsimile message is not capable of being stored in the machine, the IFAX may generate an overflow indicator. Alternatively, the IFAX may route the incoming facsimile message according to a set of overflow routing instructions.

In an alternative embodiment, the IFAX is coupled to a communication link. It comprises the steps of detecting a signal on the communication link indicating the arrival of an incoming facsimile message from a second IFAX. The first IFAX receives the incoming facsimile message over the communication link and stores the incoming facsimile message. The first IFAX then relays the incoming facsimile message to a third IFAX in accordance with a set of relay instructions.

The relay instructions may instruct the first IFAX to relay all incoming facsimile messages to a predetermined IFAX. Alternatively, the relay instructions may contain a relay prefix instructing the first IFAX to relay the incoming facsimile message to the third IFAX associated with the relay prefix. The method may include the further step of checking the predetermined list of authorized IFAXs to determine if the third IFAX is on the authorized IFAX list. The second IFAX will relay the incoming facsimile message only if the third IFAX is in the list.

The relay instructions may also contain a set of nested relay instructions, with the method further including the step of transmitting the set of nested relay instructions from the first IFAX to the third IFAX with the third IFAX using the set of nested relay instructions to relay the incoming facsimile message to a fourth IFAX in accordance with the set of nested relay instructions. The method may include the further step of checking a predetermined list of authorized IFAXs to determine if the fourth IFAX is in the list with the third IFAX relaying the incoming facsimile message only if the fourth IFAX is on the list. Alternatively, the first IFAX may contain a set of predetermined relay instructions.

In an alternative embodiment, the IFAX having a plurality of status sensors monitors the operation of the IFAX using the status sensors. The IFAX detects an error condition indicated by the status sensors and, in response to the detection of the error condition, generates an error message. The facsimile automatically notifies a key operator by routing the error message to the key operator.

The error message may be routed to a key operator computer coupled to the IFAX. Alternatively, the error message may be routed to an individual user other than the key operator if the error message is related to a facsimile operation requested by the individual user. The error message may be routed to the individual user's computer.

DETAILED DESCRIPTION OF THE INVENTION

As shown in the drawings for purposes of illustration, the present invention is embodied in an IFAX 10 and a simple method for using the IFAX which does not require extensive training. A user interface described herein allows a user with little or no training in the use of the IFAX to take full advantage of all the highly sophisticated technical features provided on the modern IFAX. The various menus and displays utilized allow the user to see at a glance, all the relevant options available to the user. When the user selects a particular option, the user interface displays other appropriate menus or takes some action dependent on the particular menu and the particular user selection.

The IFAX 10 containing the user interface of the present invention is shown in the functional block diagram of FIG. 1. The IFAX 10 contains a central processing unit 12, and a memory 14, which may comprise a random access memory (RAM), a nonvolatile RAM (NV-RAM), and a read-only memory (ROM). In addition, the IFAX 10 has a timer 16 and a user interface element 18. The user interface element 18 contains a display 20, which utilizes a touch-sensitive screen 22. The touch-sensitive screen 22 overlays the display 20 in a well-known manner to form a touch-sensitive display 24. A selection is entered on the touch-sensitive display 24 by pressing on a predetermined position of the touch-sensitive display. The selection is indicated on the display 20 by showing the predetermined portion of the touch-sensitive display 24 as a button in a depressed, or selected, position when the user initially touches the touch-sensitive display. The action associated with the selection is performed when the user removes his finger from the predetermined portion of the touch-sensitive display 24. Thus, the IFAX 10 indicates a selection when the user touches the touch-sensitive display 24, and reacts to the user removing his finger by performing the action associated with the selection. The user may change selections by sliding his finger to a different location before removing his finger from the touch-sensitive display 24. The selection process will be discussed in detail below. The user interface element 18 also includes an optional hardware numeric keypad 26 to provide an alternative method of selection by data entry.

The IFAX 10 has a file storage unit 28 such as a floppy disk unit or a hard disk. The IFAX 10 may also include serial and parallel interface hardware (not shown) to allow the FAX machine to be coupled to an external computer (not shown) or a second IFAX of the same construction. A local area network (LAN) interface 30 allows the IFAX 10 to be coupled to a LAN 32.

The IFAX 10 has a scan engine 36 to scan paper documents and create a digital image of the scanned document and a print engine 38 to print documents received from another IFAX of the same construction or prior art FAX machines. The print engine 38 may be a thermal print engine as is common in prior art FAX machines or a laser print engine. Alternatively, the IFAX 10 may be coupled to an external printer such as a laser printer. The scan engine 36 and the print engine 38 are well known in the art and will not be described in detail herein.

A data bus 40 interconnects the above-described portions of the IFAX 10 and operates in a manner well known to those of ordinary skill in the art. The IFAX 10 with a laser print engine 38 may act as a laser printer when coupled to the external computer (not shown). A FAX modem 42 couples the IFAX 10 to a telephone line 44. The FAX modem 42 provides the necessary circuitry to provide the standard facsimile tone frequencies. The standards for facsimile transmission are established by The International Telegraph and Telephone Consultative Committee (CCITT). References to CCITT standards will be made throughout this disclosure. The CCITT standards are well known and will not be discussed in detail.

An operational flowchart for the IFAX 10 is shown in FIG. 2. When the IFAX 10 is first powered up, or is reset, a Main Menu 50, shown in the screen display of FIG. 3, is displayed on the touch-sensitive display 24. The following description is best understood in conjunction with the flowchart of FIG. 2 and the display of FIG. 3. The Main Menu 50 includes entries for the most important and frequently used options that a user selects. The user may select a Send a Fax option by touching a "Send A Fax" button 52, a Mailbox option by touching a "Mailbox" button 54, a Toolbox option by touching a "Toolbox" button 56, an AutoKeys option by touching an "AutoKeys" button 58, or a Sign In option by touching a "Sign In" button 60. Details of operation of each of these options is provided below.

The touch-sensitive display 24 is designed so that the options are displayed with the appearance of buttons. A selected option appears to have its associated button in a depressed position so that the user can determine at a glance which option is selected and which options are not selected. The buttons are labeled for easy interpretation by the user and provide the inputs for IFAX 10. The user simply touches the touch-sensitive display 24 in the location corresponding to a button corresponding to the option desired, such as the Send A Fax button 52. As the IFAX 10 changes from one menu to another, the touch-sensitive display 24 is also changed so that the predetermined input portions to be touched by the user always correspond to the labeled buttons.

The IFAX 10 uses a series of context-sensitive display menus to simplify the user interaction. For example, entering numbers on the optional hardware numeric keypad 26 (see FIG. 1) relates to entering a facsimile telephone number if the user is sending a facsimile message, but relates to entering a new recipient telephone number if the user is in a different mode of operation.

A prompt 48 is displayed on a portion of each menu to provide the user with instructions or information related to the operation of the IFAX 10.

The prompt 48 may contain graphical symbols and words to instruct the user what action may be taken next. The prompt 48 changes for each of the screen displays displaced on the touch-sensitive display 24.

Selection of the Send A Fax option by touching the Send A Fax button 52 begins the process of sending a facsimile message. This option permits the user to send one or more facsimile messages to designated recipients as well as the selection of various options related to sending a facsimile message. The Send a Fax option man involve the use of the numeric keypad 26 (see FIG. 1) and a phonebook 62 (see FIG. 2) that stores the telephone numbers of other IFAX of the same construction and prior art FAX machines. The user can select a stored cover page 64 for a facsimile message and may attach enclosures 66 such as a data file that will accompany the facsimile message, and can alter settings 68 on the IFAX 10 associated with scanning a document, such as contrast.

Selection of the Mailbox option by touching the Mailbox button 54 allows the user to view and print received facsimile messages as well as modify outgoing facsimile messages. The Mailbox option uses an inbox 70 that stores received facsimile messages, and an outbox 72 that stores outgoing facsimile messages. The designation of inbox 70 and outbox 72 are terms easily understood by the user to describe documents waiting to be read (Inbox) and documents waiting to be transmitted (Outbox). The number of received facsimile messages and outgoing facsimile messages is updated on the touch-sensitive display 24.

Selection of the Toolbox option by touching the Toolbox button 56 allows the user to change both user and system settings, print reports or install, remove, or run IFAX Tool applications. The Toolbox option uses a setup control 74 to alter the user and system settings, a reports control 76 to print reports on usage of the IFAX 10, and tool applications 78. Tool applications 78 will be explained in greater detail below.

Selection of the AutoKeys option by touching the AutoKeys button 58 allows the user to define or run macros. The Sign In option selected by touching the Sign In button 60 allows the user to log in with his particular password. When a user logs in, any previously altered user settings are updated. These features will be explained in greater detail below.

Operation of the IFAX 10 can be best understood in conjunction with the operational flowcharts of FIGS. 4A-4L. The main menu flowchart is shown in FIG. 4A. As seen in FIG. 4A, the IFAX detects a user input at step 1000. In decision 1002, the IFAX determines whether the Send Fax button was depressed. If the Send Fax button was depressed, the result of decision 1002 is YES, and the IFAX goes to the Send A Fax function in step 1004. If the Send Fax button was not depressed, the result of decision 1002 is NO, and in decision 1006 the IFAX determines whether the Mailbox button was depressed. If the Mailbox button was depressed, the results of decision 1006 is YES and the IFAX 10 goes to the Mailbox function in step 1008. If the Mailbox button was not depressed, the result of decision 1006 is NO, and in decision 1010, the IFAX 10 determines whether the Toolbox button was depressed. If the Toolbox button was depressed, the result of decision 1010 is YES, and in step 1012 the IFAX 10 goes to the Toolbox function. If the Toolbox button was not depressed, the result of decision 1010 is NO, and in decision 1014 the IFAX 10 determines whether the Autokeys button was depressed.

When the user selects the Send a Fax option by touching the Send A Fax button 52, the IFAX 10 changes the touch-sensitive display 24 to the display of FIG. 5. As shown in FIG. 5, the IFAX 10 displays a numeric keypad 80 on the touch-sensitive display 24 or the optional hardware numeric keypad 26 (see FIG. 1). The optional hardware numeric keypad 26 contains a plurality of numbered buttons corresponding to the numeric keypad 80 displayed on the touch-sensitive display 24. The numeric keypad 80 operates in the same manner as the optional hardware numeric keypad 26.

A "Numbers" button 82 on the touch-sensitive display 24 is shown in a depressed position to indicate that the numeric keypad 80 is selected. The IFAX 10 selects the numbers button 82 as the default display because the most common user action is to enter a facsimile telephone number of a facsimile recipient. The prompt 48 at the top of the touch-sensitive display 24 instructs the user to enter a facsimile telephone number. The user enters the telephone number of the FAX machine to which a facsimile message will be sent (i.e., a facsimile recipient) using the numeric keypad 80 on the touch-sensitive display 24 or the optional hardware numeric keypad 26 and presses an OK button 99. Alternatively, the user may enter the name of the person or company as the facsimile recipient. The user may cancel the facsimile telephone number selection at any time and return to the main menu shown in the screen display of FIG. 3 by pressing a "Cancel" button 98.

If the user elects to enter the name of the facsimile recipient, the user selects a "Letters" button 84 on the touch-sensitive display 24. The IFAX 10 displays a typewriter style keyboard 86 on the touch-sensitive display 24, as shown in FIG. 6, if the Letters button 84 is selected. Note that the Letters button 84 is now shown in the depressed position to indicate that the typewriter keyboard 86 is selected. Alternatively, the user may depress a "Fax Number" button 88 indicator or a "Name" button 90 on the touch-sensitive display 24 to select the numeric keypad 80 and the typewriter keyboard 86, respectively. The IFAX 10 recognizes either the Fax number or the Name as a valid selection of the facsimile recipient. Thus, the IFAX 10 is designed to permit the user to select options by a variety of different techniques, some of which are redundant, for the sake of simplifying operation by the user.

The user may also select a "Symbols" button 92 to enter symbols such as parentheses. The touch-sensitive display 24 displays a symbols keypad 94, shown in FIG. 7, when the Symbols button 92 is selected. Note that the Symbol button 92 is shown in the depressed position in FIG. 7 to indicate that the symbols keypad 94 has been selected.

A "Clear" button 96 man be used as a backspace to delete the previous digit in any of the displays of FIGS. 5 to 7. The user can cancel the entire selection process by pressing the Cancel button 98. The IFAX 10 will cancel the Send a Fax option 52 and return to the main menu shown in the screen display of FIG. 3.

When preparing to send a facsimile messaged the user may not recall the facsimile number or name of the facsimile recipient. The IFAX 10 uses the phonebook 62 (see FIG. 2) to store a plurality of facsimile telephone numbers and names. The phonebook 62 is selected by depressing and releasing a "Phonebook" button 100 on the touch-sensitive display 24, shown in FIG. 5. When the phonebook 62 is selected, the IFAX 10 changes to the screen display of FIG. 8 on the touch-sensitive display 24. The operational flowchart of the phonebook 62 has been previously described in connection with FIG. 4D.

The phonebook 62 contains an index 102 that allows the user to quickly move to the desired portion of the phonebook. In the example shown in FIG. 8, the index 102 divides the phonebook 62 into five alphabetical portions, covering A-E, F-I, J-O, P-T, and U-Z, respectively. The index 102 can be divided into any desired number of portions for the convenience of the user. The user selects a portion of the phonebook 62 by selecting the corresponding portion of the index 102. Alternatively, the user may use a pair of arrow keys 104 to scroll up or down through the phonebook 62 in a well-known manner. The prompt 48 instructs the user to touch the desired names listed on the touch-sensitive display 24 and press an "OK" button 105 to indicate acceptance of the selection. The user selects the desired name and facsimile phone number from the phonebook 62 by touching the desired entry from the list displayed on the touch-sensitive display 24 in the manner described above. The user may cancel the selection process, and return to the main menu shown in the screen display of FIG. 3, by pressing the Cancel button 98, as previously described.

The user may enter new names and numbers by selecting a "New" button 108. The IFAX 10 changes the prompt 48 to instruct the user to enter the new individual name, facsimile number, company name, voice number, and street address. Alternatively, the user may edit an existing entry in the phonebook 62 by selecting the entry to be edited and selecting an "Edit" button 110. The IFAX 10 changes the prompt 48 to instruct the user to edit the selected entry in the phonebook 62. The user may also remove an entry from the phonebook 62 by selecting the entry to be removed and selecting a "Remove" button 112. The IFAX 10 displays a message for the user to confirm the deletion. If the user confirms the deletion, the IFAX 10 removes the selected entry and returns to the screen display of FIG. 8.

When the user has selected an entry from the phonebook 62 or entered a name or facsimile number, the IFAX 10 automatically switches to the next menu to complete the transmission of the facsimile message. The touch-sensitive display 24 changes to the screen display shown in FIG. 9. The IFAX 10 changes the prompt 48 to indicate to the user what facsimile telephone number has been selected by the user. The user presses a "Send Now" button 120, or a "Send Later" button 122 to select the desired time for facsimile transmission. The user may wish to send an important facsimile message immediately without regard to the cost for sending the facsimile message. Alternatively, the user may elect to delay sending the facsimile message until a later time, such as late an night when the telephone rates have decreased.

If the user selects the Send Now button 120, the IFAX 10 changes the touch-sensitive display 24 to that of FIG. 11. The user confirms that the facsimile message should be sent immediately by selecting a "Continue" button 144. Alternatively, the user may stop the facsimile transmission by selecting a "Stop" button 142. The prompt 48 in FIG. 11 uses a well-known symbol indicating that all is well with the IFAX 10.

If the user selects the Send Later button 122 (see FIG. 9), the IFAX 10 changes the touch-sensitive display 24 to that shown in the screen display of FIG. 12. The user presses a "Choose Time" button 146 to enter the desired transmission time, or a "Use Discount Rates" button 148 to use the discount telephone rates to determine the transmission time. The user can select the transmission time by pressing one of a pair of time set arrows 150 and the time display indicators. For example, the user can change "PM" to "AM" by simply touching an AM/PM button 152. Similarly, the hour can be changed by touching an hour button 153 and the time set arrows 150. The user can save the selected time as a default time by pressing a "Save as Default" button 154. The facsimile message is stored in the IFAX 10 along with the user-specified transmission time. The user may cancel the Send Later option and return to the menu shown in FIG. 9 by pressing a "Cancel" button 156. The prompt 48 instructs the user to set the desired transmission time and touch a "Start" button 157. Thus, the prompt 48 provides simple instructions to the user that are menu dependent and allow a user with little or no training to select from the various options available on the IFAX 10. The prompt 48 is tailored to the particular options available on the IFAX 10.

The IFAX 10 can be configured to print a confirmation report when a facsimile message is transmitted. The confirmation report is printed immediately following the actual transmission of the facsimile message, whether the user presses the Send Now button 12 on the Send Later button 122.

The user may also add another recipient by selecting an "Add Recipient" button 124 (see FIG. 9). Selecting the Add Recipient button 124 will return the user to the menu shown in FIG. 5 and the prompt 48 instructs the user to enter the facsimile telephone number and name of the new facsimile recipient.

The user can review the entire list of recipients by pressing a "Recipient List" button 140 (see FIG. 9). Selecting the Recipient List button 140 will cause the IFAX 10 to change the contents of the touch-sensitive display 24 to the screen display shown in FIG. 10. The prompt 48 changes to indicate that a facsimile recipient telephone number has been selected. The user may add recipients manually using the Add Recipient button 124, or from the phonebook 62 by the selecting an "Add From Phonebook" button 139. The user may edit any facsimile recipient information by selecting the desired facsimile recipient and selecting an "Edit" button 134. The user may also remove a facsimile recipient from the list by selecting the desired facsimile recipient and pressing a "Remove" button 136. The user may add carbon copy (Cc) recipients by selecting a "Cc" button 138.

Returning now to FIG. 9, the user man specify a facsimile cover page by pressing a "Select Cover Page" button 126. If the user presses the Select Cover Page button 126, the IFAX 10 changes to the screen display of FIG. 13. The prompt 48 instructs the user to fill out the cover page. The user enters data into the appropriate portions of the touch-sensitive display 24. If the user presses a "Cover Style" button 160, a "Subject" button 161, or a "Comments" button 163, the IFAX 10 displays the typewriter keyboard 86 such as shown in FIG. 6 on the touch-sensitive display 24, and the prompt 48 instructs the user to fill in the appropriate information. Similarly, if the user presses a "Number of Pages" button 165, the IFAX 10 displays the numeric keypad 80 such as shown in FIG. 5 on the touch-sensitive display 24, and the prompt 48 instructs the user to fill in the appropriate information. The user can save this information as default values by selecting the Save as Default button 154 previously described. The user man cancel the selection process at any time and return to the menu shown in the screen display of FIG. 9 by pressing the Cancel button 156. The user presses the OK button 158 to verify that the data entered is correct. The user may also select a Facsimile cover page style from a list of stored facsimile cover pages by selecting the "Cover Style" button 160. The cover pages are stored in the memory 14 or the file storage unit 28 for future use.

In response to the selection of the Cover Style button 160, the IFAX 10 changes to the display of FIG. 14 where a list of stored digital images of facsimile cover pages is displayed on the touch-sensitive display 24. The prompt 48 instructs the user to select the cover style. The stored facsimile cover pages are digital cover pages that can be customized for particular facsimile recipients or for particular facsimile messages. The IFAX 10 can store a plurality of digitized cover pages in the file storage unit 28 (see FIG. 1). The user may create digitized cover pages in any number of manners well known to those skilled in the art. For example, the user could use the Microsoft® PaintBrush™ program to create a digital cover page. The user-created cover page is stored in the memory 14 or the files storage unit 28 and is added to the list of cover page styles shown in FIG. 14. The digital cover page is stored in the form of a bit-map. The bit-map can be compressed by any number of well-known data compression routines in order to save space in memory 14 or the file storage unit 28. The user selects one of the facsimile cover pages from the list of FIG. 14 by touching the touch-sensitive display 24 at the location where the desired facsimile cover page style is listed. If the list of facsimile cover pages exceeds the number that can be displayed at one time, the user may use the arrow keys 104 to scroll the list in the desired direction. When the user selects the desired facsimile cover page by touching one of the cover pages listed on the touch-sensitive display 24, the selection is verified by pressing the OK button 158. The user may also cancel the selection process at any time and return to the menu shown in the screen display of FIG. 13 by pressing the Cancel button 156.

Returning again to the display of FIG. 9, the user may also enclose one or more data files with the outgoing facsimile message by pressing an "Enclose A File" button 128. The enclosed data file may be any data file such as a word processor data file or a spreadsheet data file. The data file is typically stored in the file storage unit 28. When the user selects the Select A File button 128, the IFAX 10 changes to the display of FIG. 15. The prompt 48 instructs the user to select the data file(s) to be transmitted as part of the facsimile message. In the screen display of FIG. 15 no data files are enclosed. If data files are enclosed, they would be listed on the screen display of FIG. 15. The user can remove a data file from the enclosure list, selecting the desired data file by touching the one or more files listed on the touch-sensitive display 24, then pressing the Remove button 136 as previously described in connection with FIG. 10.

The user may select a data file to enclose by pressing a "Select Files" button 164, which causes the IFAX 10 to change to the display of FIG. 16. The prompt 48 instructs the user to select a file from one of the folders listed on the touch-sensitive display 24. The user can cancel the enclosure selection process by pressing the Cancel button 156, which causes the IFAX 10 to return to the menu shown in the screen display of FIG. 15. In FIG. 16, the folders shown are the inbox 70 (see FIG. 2), where incoming facsimiles are stored by the IFAX 10, a floppy disk or other file storage unit 28 (see FIG. 1), or special attachments. The user may touch one of the folders to open that folder and display the contents of the selected folder.

For example, the user can open the inbox 70 (see FIG. 2) and display the files enclosed in the inbox by touching the inbox folder display location on the touch-sensitive display 24. The user selects a data file from the inbox 70 and encloses the selected file by pressing an "Enclose" button 170. This causes the IFAX 10 to return to the menu shown in the screen display of FIG. 15 which shows the enclosed data file in the list displayed on the touch-sensitive display 24. The enclosed data file may be a binary data file or a scanned facsimile message stored in the well-known MH, MR, or MMR data formats used in Group 3 FAX machines. Thus, the IFAX 10 allow s the user to easily attach a data file to the facsimile message. The user can close the select enclosure menu of FIG. 15 by pressing a "Close" button 166. Pressing the Close button 166 causes the IFAX 10 to return to the menu shown in the screen display of FIG. 9 so that the user can complete the process of sending the facsimile message.

Returning again to the display of FIG. 9, the user can also set other option parameters by selecting a "Set Other Options" button 130. In response to the selection of the Set Other Options button 130, the IFAX 10 changes to the screen display shown in FIG. 17. The prompt 48 instructs the user to select the parameters that the user wishes to change. The user selects the desired option by touching the desired option listed on the touch-sensitive display 24 and selecting a "Change" button 172. As seen in FIG. 17, the user can alter scanner settings by selecting a "Scanner Settings" display location 176, the security settings by selecting a "Security Settings" display location 178, the department code settings by selecting a "Department Code" display location 180, and the miscellaneous settings by selecting a "Miscellaneous" display location 182. It is obvious that the options presented herein are merely illustrative of the tapes of options that could be included in the menus. Other options could be added or revised to fit the particular needs of the user.

If the user selects the Change button 172 without first selecting a category to change, the IFAX 10 displays an error message, shown in the screen display of FIG. 18, which instructs the user to first select a category to modify, then press the Change button 172. Thus, the IFAX 10 instructs the user when in inappropriate selection has been made. These instructions allow the user to easily recover from an error. In prior art FAX machines, the user may not be aware that an error has been made. Furthermore, the user is unlikely to recover from the error in such an easy manner on a prior art FAX machine. Typically, the user would have to start the entire process over again and hope that the error is not repeated. This lack of error recovery often leads to frustration of the user and subsequent intimidation of the user by the complicated process of sending a facsimile message. In contrast, the user friendly environment created by the IFAX 10 leads the user through a complex list of options and provides instructions to the user in the proper operation of the IFAX. The IFAX 10 also permits the user to send and receive facsimile messages without the selection of the sophisticated options and capabilities that the FAX machine man possess.

The Scanner Settings display location 176 shown in the screen display of FIG. 17 allows the user to select settings such as resolution and contrast. If the user selects the Scanner Setting display location 176 and presses the Change button 172 the IFAX 10 changes to the display shown in FIG. 19. The prompt 48 instructs the user to change the scanner settings and press the OK button 158. The user changes the settings by selecting any of the options shown in FIG. 19 using the corresponding buttons. The user selects the desired setting and then presses the "OK" button 158 to confirm the choices. The user may save the selected options as default values by pressing the Save As Default button 156. The user may also cancel the selection of scanner settings at any time by selecting the Cancel button 154. This cause the IFAX 10 to return to the menu shown in the screen display of FIG. 17.

The Security Settings display location 178 shown in the screen display of FIG. 17 allows the user to select options such as data encryption or authentication. If the user selects the Security Settings display location 178 and presses the Change button 172, the IFAX 10 changes to the screen display shown in FIG. 20. The touch-sensitive display 24 shows which options are currently selected, and the prompt 48 instructs the user to select security options and press the OK button 15 8. Options that have previously been selected may be deselected by touching the corresponding button and selecting the OK button 156. The IFAX 10 permits encryption of a facsimile message by selecting an "Encryption" button 190. In addition, the IFAX 10 permits the transmission of a digital signature by selecting a "Digital Signature" button 192, and an authentication option by selecting an "Authentication" button 194. The digital signature causes the IFAX 10 to transmit a checksum or other data portion in encrypted form along with the encrypted facsimile message. The digital signature allows the receiving facsimile machine to determine if the facsimile message has been tampered with during transmission. The authentication option attaches an instruction to the facsimile message requiring a password to be entered into the recipient facsimile machine for the facsimile recipient to read the facsimile message. Thus, there are varying degrees of security that may be easily selected by the user. The user may save the selected options as default values by selecting the Save As Default button 154. The user may also cancel the selection of security settings at any time by selecting the Cancel button 156. This cause the IFAX 10 to return to the menu shown in the screen display of FIG. 17.

With reference to FIG. 17, the Department Code display location 180 allows the user to enter a department code. If the user selects the Department Code display location 180 and presses the Change button 172, the IFAX 10 changes to the screen display shown in FIG. 21. The prompt 48 instructs the user to press a "Department Code" button 196 to enter the department code. The user enters the appropriate information and presses the "OK" button 158 to confirm the choice. The user may save the selected choices as default values by pressing the Save As Default button 154. The user may also cancel the selection of department code settings at any time by pressing the Cancel button 156. This cause the IFAX 10 to return to the menu shown in the screen display of FIG. 17.

With reference to the screen display of FIG. 17, the Miscellaneous display location 182 allows the user to select miscellaneous options such as sending from memory and including a fax header on the facsimile message. If the user selects the Miscellaneous display location 182 and presses the Change button 172, the IFAX 10 changes to the screen display shown in FIG. 22. The prompt 48 instructs the user to select the desired options. The user can send a facsimile message from memory by pressing a "Send From Memory" button 200. The user can also elect to include a header, number the pages, print a confirmation report on the IFAX 10, and enable turnaround polling by pressing an "Include Fax Header" button 202, a "Number Pages" button 204, a "Print Confirmation Report" button 206, and a "Turnaround Polline" button 208, respectively. The user selects the desired options and then presses the "OK" button 158 to confirm the choices. The user may save the selected options as default values by selecting the Save As Default button 154. The user may also cancel the selection of miscellaneous settings at any time by selecting the Cancel button 156. This cause the IFAX 10 to return to the menu shown in the screen display of FIG. 17.

Most of the miscellaneous options described above are self-explanatory. The Turnaround polling option causes the IFAX 10 to send a facsimile message to the facsimile recipient FAX machine and then inquire whether there any facsimile messages that are to be sent to the IFAX 10 from the facsimile recipient FAX machine. If there are messages to be sent to the IFAX 10, the IFAX can receive these messages during the same telephone call thus minimizing both the time and cost for facsimile communication.

Thus, the IFAX 10 permits an untrained user to easily select from among the many options available on a facsimile machine to send a facsimile message. The user can select the transmission time, enclose files, add stored digital cover pages, and use a sophisticated phonebook system to select recipients for the facsimile message. The prompt 48 provides step-by-step instructions and the screen displays allow the easy selection of options.

The IFAX 10 also provides for a simple user interface to permit the user to retrieve facsimile messages received by the IFAX, and to edit stored outgoing facsimile messages that are to be sent at a later time. Returning now to the main menu shown in the screen display of FIG. 3, the Mailbox button 54 allows the user to select the mailbox options. As seen in FIG. 3, the IFAX 10 updates the touch-sensitive display 24 to show the number of messages contained in the inbox 70 and the outbox 72. Thus, the user can determine at a Lance whether there are any facsimile messages without having to actually use the mailbox features.

When the user presses the Mailbox button 54, the IFAX 10 changes to the display of FIG. 23 which displays the features of the inbox 70. The Mailbox function has been previously described in connection with the operational flowchart of FIGS. 4E-4F.

If Access Restriction is on and the recipients are not members of the phonebook, abort the call and print an error report "Access restriction is currently limited to members of the phonebook. This destination is not in the phonebook."

If the Automatic Relay Fax Request is configured, setup the Send operation through the proper relay station (usually by recipient area or country code). The relay station becomes the recipient. See the Automatic Relay Fax Request section for more information.

If Send Later is requested, scan the entire document into the Sender's outbox. Proceed with the Send operation in the background at the time specified. If Send From Memory is requested,. scan the entire document into the Sender's outbox. Proceed with the Send operation in the background when possible.

When scanning the document, observe the user's settings for resolution, contrast, and halftoning. For more information, see the High Resolution Scan, Print, Send & Receive, Gray Scale, and Automatic and Manual Contrast Control sections.

Before beginning the transmission, check to see if other outgoing faxes are headed to the same destination fax number as seen in FIG. 98. See the Intelligent Fax Queuing and Multicasting section for more details. Also, determine if the current outgoing load factor requires network redistribution. See the Fax Load Balancing section for more information.

Dial the recipient to begin the transmission. Use the dial mode (Pulse/Tone) specified in the Phone Line Settings dialog. Wait n seconds for a carrier, where n is specified as the time to carrier in the Phone Line Settings dialog. If a carrier is detected, light the Communicating LED. Otherwise, try the recipient's alternative fax number (if available). If there is still no connection, increment the redial count and try again after the redial interval.

If the facsimile message is a Relay Fax Request, verify the relay password or the system password. If the sender does not have relay access, abort the call and issue an Error Report "You do not have relay access at this destination."

Request then update (in the Phonebook) the recipient's address entry. This obtains the entire address entry for a particular user including his public key.

Determine the transmitting resolution most appropriate for this recipient's fax machine.

If Include Digital Cover Page has been selected, generate it as the first page of the transmission. If the recipient fax machine is Intelligent, just send the cover page as a binary header. Otherwise, render the cover page for transmission. The default cover page style is described in the Digital Cover Page Section.

If Include Personal Header is on, include the following header at the top of each transmitted page (after the cover page). The header should contain the Sender's Name, Fax Number, Company Name and Date (as shown below).

    ______________________________________     Mr. James Smith                Microsoft Corporation                               September 15, 1992     (206) 555-5555     ______________________________________

If Number Outgoing Pages is on, transmit the page count at the bottom right corner of each page. If the Number of Pages has been specified in the Cover Page dialog, use the page numbering style 1/4, 2/4. 3/4, 4/4 otherwise number them sequentially 1, 2, 3, 4.

Scan each page checking for OMR Fax Stacking headers. If there is no header, transmit each page and continue. If an OMR header appears, complete the transmission without transmitting any subsequent pages. See the High Resolution, Scan, Print, Send & Receive section for details on transmitting resolutions and paper size.

Send any binary attachments. If Send Renderable is selected, render any attachments of supported file types. See the High Quality Renderable Document Transmission section for details. If sending to a G3 Machine, render a "This Intelligent Fax Message contains a binary file which your fax machine does not support." message.

If Encryption is selected, encrypt all transmission data using the recipient's public key.

If Digital Signature is selected, compute a hash code on all transmitted data. Encrypt and transmit the hash code at the end of the call with the recipient's public key.

If Authentication is selected, transmit the sender's Digital Certificate.

As seen in FIG. 99, if Turnaround Polling is selected, poll the recipient's IFAX Machine for Personal Messages. Issue a Poll Retrieve Results report and route it with any retrieved messages according to the Sender's Receive Fax settings. See the Poll Retrieve section for more information.

When the transmission is complete, hang up the line. Turn off the Communicating LED.

Check that the number of pages transmitted matched the number specified by the user (if available). If the number of pages does not match, issue an error report. Log any other transmission errors that occurred.

Enter the results into the Activity Report (TCR) with the name of the currently signed in user (or Public) and the Department Code (if specified).

If Print Confirmation Report is on, issue a Confirmation Report. See the Basic Activity Reporting section for more information.

Exceptions:

    ______________________________________     Connection Lost                  If the carrier is found but the line is interrupted                  during the send, abort the operation and issue a                  "Connection was lost" Error Report.     Document Cover Open                  Display a dialog to give the user 15 seconds to                  close the Document Cover. If it is not closed,                  abort the operation and issue an Error Report.     Memory Full  If a Memory Full condition occurs on a Send                  From Memory, begin the transmission. Send                  the part that has been stored in memory and                  scan and transmit the rest on-the-fly.                  If a Memory Full condition occurs on a Send                  At Discount Rates or Send At Scheduled Time,                  display the "Out of memory. Holding fax in                  feeder until Time xx:xx" dialog                  box. Complete the Send at the specified time.     No Connection                  If the line is busy or no carrier is found, the                  Alternative Fax Number should be tried (if                  available). If this too fails, the number of                  retries should be incremented. If it is equal to                  the standard number of retries, issue an                  "No Connection" Error Report. Otherwise,                  re-initiate the send after the retry interval.     OMR Cover Page Invalid                  Abort the call. Issue an "OMR Cover Page                  Invalid" Error Report.     Paper Jam    Abort the Send operation and issue an Error                  Report. Display the "Paper Jam" dialog box.     Power Off    Issue an Error Report after the next Power                  On indicating that the interruption occurred.     Public Key Missing                  If the public key cannot be obtained, abort the                  call and issue a "Can't obtain public key"                  Error Report.     Stop         Abort the operation. Issue an Error Report and                  indicate the page in which the interruption                  occurred.                  If the send is in the background, check if the                  user has authority to stop the current send                  process. If so, display a "Interrupt                  transmission?" dialog box. Otherwise, display a                  "You do not have access to this transmission."     Transmission Error                  If the Number of Pages scanned and                  transmitted does not correspond to the                  number specified by the user, issue a "Did                  not transmit page x of y" Error Report.     ______________________________________

Receive Fax

Description:

The IFAX 10 can receive faxes from both Intelligent and G3 fax machines. Received messages can be printed, stored in mailboxes, forwarded to PC's connected via LAN or Serial or routed to a Tool Application for special handling or OCR.

Intelligent messages are typically routed directly to their recipient, either to their mailbox or their PC.

G3 messages are typically printed or routed to a special mailbox. However, when a special OMR cover sheet is included in the G3 fax, IFAX machines can interpret them and route them as an intelligent fax message. IFAX machines can also route G3 faxes to special Tool Applications that will properly route them using OCR or other methods.

IFAX machines also support on-screen preview of received faxes from the Mailbox.

Options:

Print Received Faxes is the standard default. Each incoming fax is printed as it arrives.

Store In Mailbox lets the user retrieve their messages at their convenience while adding an extra level of security.

Forward To PC actually routes the faxes directly to the users PC via LAN or Serial.

Forward To Tool Application routes the fax to a specific Tool Application for special handling. OCR Tools will probably be the most frequently used.

Multi-Document Sort prints multiple copies of each incoming fax.

Reverse Order Printing prints received faxes back-wards so that the pages will be in the proper order.

Automatic Paper Selection prints incoming messages on paper that most closely fits the size of the document being received (on systems with multiple paper sources). If desired, the user can manually select the paper source instead.

Automatic Reduction can adjust slightly oversized received messages to fit the available paper supplies. If the difference is extreme, page breaks will be used.

Procedure:

As seen in FIG. 100, after detecting the Number of Rings specified by the Administrator, answer the incoming call. If a carrier is detected, light the Communicating LED.

Display a Receiving Fax dialog box. This notifies the user that a fax is coming in. If a user is present, he can simply touch Continue to regain control of the User Interface. If no one presses Continue, remove the dialog when the Receive is completed.

Determine if the incoming message is G3 or EFAX.

If the incoming message is an EFAX Message, handle it according to the user's Routing Setup:

Print on the IFAX

Route to the user's mailbox

Route to user via LAN/Serial

Secure Faxes routed to user's Mailbox/Others Printed

Faxes to unknown users are routed to the G3 Operator destination (see below).

If the message contains a binary Attachment, always route it to the User (not printed) or his Mailbox.

Note: All automated activity reports should be routed according to the Sender's receive settings.

If the incoming message is Encrypted, decrypt it using the recipient's private key. If the private key is not available or if the user is unknown store the document as an encrypted message.

If the incoming message is Digitally Signed, compute a hash code on all incoming data. Decrypt the incoming hash code and compare the two. If they are not equal, issue an Error Report "Document has been tampered with," and enter it into the Error Log.

If the incoming message requests Authentication, decrypt the sender's Digital Certificate and use it to decrypt the message.

If the incoming message is a G3 Message, check to see if it has an IFAX OMR cover page. If so, obtain the addressing information; see the Automatic G3 OMR Cover Sheet Recognition section for more information. Route the message as an EFAX Message (see above).

If there is no IFAX OMR cover page, the G3 fax should be routed according to the following settings:

Route to Automated G3 Inbound Routing Support Feature

Route to PC Based G3 Routing Application via LAN/Serial

Route to specific G3 Operator via LAN/Serial

Route to specific G3 Operator Mailbox

Printed by the IFAX

If the Automated G3 Inbound Routing Feature is used, route the fax according to the resulting Recipient's EFAX Routing Setup (once this information has been obtained).

Use the G3 TTI to indicate the sender of G3 faxes in the users Inbox listing.

Enter the reception results in the Activity Report (TCR). If the Print Reception Reports option is on, issue a Reception Report as described in the Basic Activity Reporting section.

If the Public Mailbox is specified as the G3/unknown fax destination. always print the Reception Report.

If the Store Received Phonebook Entries option is on, cache the Sender's Address Information and public key in the Recipient's Phonebook.

Exceptions:

    ______________________________________     Connection Lost                 If a Phone Line Interruption occurs during the                 receive, issue a "Connection Lost" Error Report.     Document Cover Open                 Display the Document Cover Open dialog. If it is                 not closed within 15 seconds, abort the receive                 operation. Issue an Error Report once the Paper                 Feed is closed.     Mailbox Full                 If the Recipient's Mailbox is Full, print the                 message.                 If the message is Secure or contains a binary                 Attachment, abort the operation, issue a                 "Mailbox Full" Error Report and instruct the                 calling machine to try again later.     Memory Full Display the Memory Full dialog box. If the IFAX                 runs Out of Storage (disk space/memory), the                 message should be treated as above in                 Mailbox Full.     Paper Jam   Display the Paper Jam dialog box. Route the                 remainder of the message to the user's mailbox                 (if possible). Otherwise, or if the mailbox                 becomes full, abort the operation and issue                 an error report. If the error report is to be                 printed, store it until the paper jam is fixed.     Paper Out   Display the Paper Out dialog box. Route the                 message to the User's Mailbox (Public Mailbox                 if G3). If no Mailbox storage is available,                 abort the Receive operation and issue an Error                 Report. If the error report is to be printed, store it                 until there is paper.     Power Off   Issue an Error Report and route it with the                 partially received message at the next Power On.     Stop        Abort the operation. Disconnected the line                 and clear the paper feed on the printer.                 If the receive is in the background, check if the                 user has authority to stop the current process.                 If so, display a "Interrupt reception?" dialog                 box. Otherwise, display a "You do not have                 access to this reception."     Transmission Error                 If the Number of Pages received does not                 correspond to the number specified by the                 message header, notify the Sending machine and                 issue an Error Report.     ______________________________________

High Resolution Scan, Print, Send & Receive

Description:

IFAX platforms can scan, print, send and receive at a variety of resolutions. We presently support the following bitmap resolutions:

Options:

203×98 (Vertical by Horizontal) is the low quality, economy transmission resolution.

203×196 is the Standard G3 transmission resolution.

203×392 is the high quality, fine transmission resolution.

406×392 is currently the optimal transmission resolution.

The IFAX software also supports the 200×200, 300×300 and 400×400 English scanning resolutions.

The IFAX 10 software can also be easily extended to support even higher resolutions. As processor and peripheral speeds increase with technology advancements, it is expected that the resolutions supported by both the EFAX and G3 protocols will also increase.

Procedure:

The Send Fax, Receive Fax, Broadcast Fax, Poll Retrieve, and Poll Store contain instructions for choosing optimal scanning and printing resolutions as well as paper size information.

When scanning for a remote destination via Serial/LAN Interface 30 (see FIG. 1), operate the scanner at the resolution specified by the remote configuration. See the Remote Scan Over Serial Connection feature description.

When printing from a remote destination via LAN or Serial Interface, operate the printer at the resolution specified by the remote configuration.

There are four counters on each fax machine: Scanned Pages, Printed Pages, Transmitted Pages and Received Pages. Increment the appropriate counter after each page has been scanned, printed, transmitted or received.

High Speed Send and Receive

Description:

The IFAX 10 will support transmission speeds up to 14,400 bps. It will step down to lower speeds when connected to slower machines.

While transmission speeds are approaching the current limitations of the PSTN transport media, these limitations will inevitably be extended with time. The proposed V.fast fax transmission standard is one example of this, allowing transmission at 28 kbps on connections where the subscriber loop is the only analog portion of the communications channel. The IFAX machine architecture will be designed so that higher transport speeds will not be unnecessarily precluded. These higher speeds, may, however, require the use of faster CPU's or special modem access methods.

Procedure:

The IFAX Machine should always use the maximum possible communication speed, 14.4K Baud, stepping down when connected to slower machines. The user should be isolated from selecting modem transmission speeds.

Poll Store

Description:

Poll Store retains document(s) until requested by a calling fax machine. IFAX platforms support extended G3 Polling: File Number Password. EFAX Polling: File Name+optional Password, and free access retrieval (public).

If sufficient memory exists in the IFAX to store the document or the IFAX is equipped with a disk, the document will be scanned and stored awaiting the polling request. Otherwise, the document will remain in the document feeder until the poll request is received. In this case, the document will only be available to the first polling machine.

Users will also be able to access a list of documents currently stored for polling in order to delete particular documents or change access information. Retrieval Reports are generated whenever a file is deleted.

Options:

In addition to all of the standard Send Fax options, Poll Store supports:

Group Store lets the user store the document for any number of recipients to retrieve. Once all of the specified recipients have retrieved the fax it is deleted from the store.

Unrestricted Access allows any caller to retrieve the document(s).

Days To Store specifies the number of days until the file should be deleted regardless of the number of retrievals.

Title specifies a filename for the given document. A file number can be specified instead.

Password restricts document access to callers that can provide this password.

Procedure:

Allows user to store document(s) and binary Attachments to be retrieved by other callers. Begin the poll store operation, shown in FIG. 101, when the user presses Start.

If Access Restriction is on and the recipients are not members of the phonebook, abort the store operation and print an error report "Access restriction is currently limited to members of the phonebook. This recipient is not in the phonebook."

If there is no document or binary file, display the "Please Insert Document" dialog box. Continue when the user inserts a document.

Scan the document according to user's settings for resolution, contrast, and gray scale settings chosen in the Poll Store Options dialog of the User Interface. See the High Resolution Scan, Print. Send & Receive, Automatic and Manual Contrast Control, and Gray Scale sections for more details.

As you place the document in the Outbox, prepare it for transmission as in Send Fax, i.e. with Digital Cover Page, Fax Header, Page Numbering, etc.

If the message is placed in the outbox 72 (see FIG. 2) without errors and the Poll Store File Report option is on, issue a Poll Store File Report. If there are errors, issue an Error Report and enter it into the Error Log. In the case of any error, the Poll Store configuration of the User Interface should be maintained, including all recipient and document information, to allow the user to easily retry the task.

Note: All reports should be routed according to the Sender's receive settings.

Remove the message from the Outbox after the number of days specified by the Days To Store option.

When the IFAX Machine is Polled for documents:

The calling machine will make a request for certain document title(s) and password(s). It may also request all publicly available documents, all documents addressed to the caller, and a list of available documents.

If it is a G3 machine, it will specify a file number plus optional password. This supports the proposed convention for handling multiple stored messages in the 1992 G3 extensions.

Check for each available document. If the document is stored for public access, transmit it to the calling machine. If the document is addressed to specific users, verify the caller's name before transmitting.

Determine the transmitting resolution most appropriate for this recipient's fax machine.

If Encryption is selected, encrypt all transmission data using the caller's public key.

If Digital Signature is selected, compute a hash code on all transmitted data. Encrypt and transmit the hash code at the end of the call with the caller's public key.

If Authentication is specified, verify the caller's identity using the Digital Certificate before transmitting.

If no documents are available, issue a Poll Results report stating that the query failed.

Once documents have been retrieved by all of the designated recipient(s), they should be removed from the outbox 72.

Exceptions:

    ______________________________________     Document Cover Open                  Display a dialog prompting the user to close it                  within 15 seconds. If it is not closed, abort the                  Poll Store. Issue an Error Report. If it is to be                  printed, hold it until the cover is closed.     Mailbox Full If the Recipient's Mailbox is too full to Poll                  Store the message, display a "Mailbox Full,                  Cancel Poll Store or leave document in                  feeder?" dialog.                  If other users remove the document to do their                  own faxing, issue an error report to the original                  sender.     Memory Full  If the IFAX runs Out of Storage (disk                  space/memory), the message should be                  treated as above in Mailbox Full.     No Attachment Support                  Poll Store documents may also contain binary                  attachments not supported by G3 callers.                  Render a "This is an Intelligent Fax Message                  Attachment which is not supported on your                  fax machine." on the calling machine.     Paper Jam    If a Paper Jam occurs, abort the operation. Give                  the user the option of clearing the Poll Store                  user interface setup or retrying once the Jam                  is fixed.     Power Off    If the IFAX is Powered Off while scanning or                  placing the message in the Outbox, issue an                  Error Report at the next Power On.     Stop         If Stop is pressed during scanning, the                  operation should be aborted. Display a dialog                  prompting the user to clear the Poll Store                  User Interface configuration. If the user                  does not respond within 60 seconds, the Poll                  Store User Interface configuration should be                  cleared and the User Interface reset.     ______________________________________

Polled Fax Retrieve

Description:

Polled Fax Retrieve allows users to retrieve documents from remote fax machines or document servers (see the Poll Store feature description). The user can specify retrieval of multiple titles from multiple poll stations.

Options:

Poll Now performs the poll operation immediately.

Poll Later performs the poll operation at a user specified time or when rates are cheaper.

Persistent Poll performs the poll operation at a user specified time and again at regular intervals (e.g. each day at 4 p.m.)

Retrieve Personal Documents specifies retrieval of documents addressed specifically to the user.

Retrieve By File Name/Number specifies retrieval of particular document(s) with optional password.

Retrieve All Public Documents specifies retrieval of any documents available for public access.

Request List of Available Documents specifies retrieval of a list of any documents that are available to this caller (including public access documents and password protected documents).

Remote Destination specifies that the retrieved documents should be forwarded to another destination.

Poll Results Report specifies that a summary report should be printed at the end of the poll retrieve operation.

Request Activity Reports requests current activity reports be routed back to the user. The user must include the system password to receive these reports.

Check Relay Status requests a status report from the destination machine for a previous fax relay request. The user must include the system password to receive this report.

Procedure:

Polled Fax Retrieve allows user to retrieve document(s) and binary Attachments stored on remote fax machines or servers. Begin the Poll Retrieve operation when the user presses Poll Now or Start as shown in FIG. 102.

If Poll Later is specified, store the request in the user's outbox until the appropriate time.

Before beginning the retrieve request, the IFAX should check to see if other outgoing faxes are headed to the same destination fax number. See the Intelligent Fax Queuing and Multicasting section for more details. It should also determine if its load factor requires network redistribution. See the Fax Load Balancing section for more information.

Dial the recipient to begin the Poll Retrieve. If a carrier is detected, light the Communicating LED. Otherwise, try the recipient's alternative fax number (if available). If there is still no connection, increment the redial count and try again after the redial interval.

If the Retrieve All Public Documents option is on, request all public documents from the Poll Station and route them according to the user's Receive settings.

If the Retrieve All Personal Documents option is on, request all personal documents and route them according to the user's Receive settings.

If the Request Activity Reports option is on, request the Activity Reports and route them according to the user's receive settings.

If Request List of Available Documents option is on, request a list of all documents (public and personal) and route them according to the user's receive settings.

If a Poll Result Report has been requested, route it with the retrieved documents (if any) to show the results of each document query.

If the Check Relay Status option is on, query the Recipient machine for Relay Fax Requests from the caller. Once this information is retrieved, the status of all the relays from this user should be routed in a Relay Status Report according to the user's receive settings.

End the call. If a Remote Destination for the documents has been specified, forward all retrieved items to the remote destination as a Send Fax operation.

If the Persistent Poll option, is specified, maintain a scheduled copy of this operation in the user's Outbox. This will implement the re-occurring poll operation on a regular basis. When the user wants to end this operation, they will delete the poll operation from their Outbox.

Exceptions:

    ______________________________________     Connection Lost                 If a Phone Line Interruption occurs during the                 Poll Retrieve, issue an Error Report and enter                 it in the Error Log. Route the incomplete Poll                 Retrieve docurnent(s) with the Error Report.     Document Cover Open                 If the Paper Feed is opened during a Poll                 Retrieve, display a "Close Paper Feed" dialog                 for 15 seconds. If it is not closed, abort the                 operation. Issue an Error Report once the Paper                 Feed is closed.     Memory Full If the User's Mailbox is too full to retrieve the                 document(s), the abort the operation. Display                 a "Clear Poll Retrieve Settings?" dialog.                 Pressing No from the Clear dialog would allow                 the user to switch to the Mailbox, clear up                 space, and retry the Poll Retrieve operation.     No Connection                 If the line was busy or no carrier is found, try the                 Alternative Fax Number (if available). If this too                 fails, increment the number of retries. If it                 is equal to the standard number of retries, issue                 a "No Connection" Error Report.                 Otherwise, re-initiate the Poll Request after the                 retry interval.     Paper Jam   Abort the operation and display a "Paper Jam"                 dialog box.     Paper Out   Route the rest of the document to the                 User's mailbox. If mailbox storage becomes                 full, abort the operation. Display an "Out                 of Paper" Dialog Box.     Power Off   Print an Error Report at the next Power On and                 route the partially received Poll Retrieve                 document(s) to the user.     Stop        If Stop is pressed during the Poll Retrieve,                 abort the operation. Display a "Clear Poll                 Retrieve settings?" dialog.                 If the user does not respond within 60 seconds,                 clear the Poll Retrieve settings.     Transmission Error                 If the Number of Pages received does not match                 the number specified by the message header,                 issue an Error Report.     ______________________________________

Broadcast Send

Description:

Broadcast send allows users to send a document to multiple destinations. It is not a separate user command, but rather an enhancement on the basic message addressing process described in the Send Fax feature description.

When two fax recipients are located on the same destination IFAX machine, the fax message will be sent only once, as discussed in the Intelligent Fax Queuing and Multicasting feature description.

Options:

Sending to multiple destinations allows the user to enter multiple fax recipients for a given message.

Group lists allow users to pre-program common broadcast lists into the Phonebook for easy access. Group lists can also be nested for enhanced distribution.

Relay Lists allow users to pre-program relay requests into the Phonebook. (See Relay Fax Request feature description). Relay requests may be entered when the recipient's information is added to the address book (as described in the Address Book Maintenance feature), or may be entered by the user when the recipient is added to the broadcast send list. Relay lists can also be nested.

Procedure:

The Broadcast procedure is the same as the Send Fax procedure except for:

Once the recipient list exceeds one user, the Send From Memory option should be used automatically.

Recipient fax numbers in the recipient list should be consolidated so that duplicate calls aren't made to the same destination. Intelligent Fax Queuing checks should also be performed (as in the Send Fax procedure).

If Include Digital Cover Page is selected, list the entire group of broadcast recipients, including Cc: recipients on the cover page.

When scanning the document, one entry should be added to the user's Outbox list for each fax recipient (at a different fax number). This allows users to see the status of and redial individual faxes within a broadcast.

If Print Confirmation Report is on, issue a summary Confirmation Report. Do not issue individual Confirmation Reports for each transmission. See the Basic Activity Reporting section for more information.

Exceptions:

Since each recipient's message is handled as a separate Send, all the same Send Fax exceptions apply.

Relay Fax Request

Description:

The user can specify that the fax should be sent via a "relay point." This relay point must be another IFAX machine, since relay is not part of the adopted G3 standard or the 1992 proposed G3 enhancements.

Relay addresses can be stored in the Phonebook for easy access or created on the fly during each send operation.

Options:

Direct Relay Combinations allow users to specify recipients that reside on the relaying IFAX machine (the relay point) in combination with other relay recipients that reside at different fax numbers.

Multiple Relay Recipients can be specified so that the relay point is actually performing a Broadcast operation.

Nested Relay Recipients can be included so that one relay point will send a broadcast list to another relay point, and so on. This enables advanced document distribution over complex corporate networks.

Discount Rate Relays control the time and costs of the relay point transfer. This option specifies that the Relay Point should forward the fax to the relay recipient during its discount rate period.

Relay Confirmation Report returns a summary of receipts and failures to the original caller.

Relay Password Security restricts access to relay point machines to callers that include a special password for fax relays. A different password may be required for each relay point.

System Password Security restricts access to relay point machines to calling machines that share the same system password as the relay point.

Automatic Relay Request allows the user to set up a system-wide table of automatic relays, as discussed in the Automatic Relay Request feature.

Procedure:

When a Relay Station is requested, the IFAX Machine sends the document to a Relay Station with the addresses of the intended recipient(s).

A Relay Fax Request consists of a Relay Station Address, a Relay List, a Relay Password and discount rate information. The Relay Station Address consists of a Name, a Fax Number and an alternate fax number. The Relay List consists of EFAX Addresses for each recipient.

To the Sender's IFAX Machine, the Relay Fax Request is handled like a typical Send operation. All the Send Options and Exceptions apply.

Once the relay station is connected, the calling system makes a relay request. The Relay Station checks the Relay Password Security. If this fails, it checks the System Password Security. If neither password is accepted, it returns an error report. However, if either of the passwords are correct, it accepts the documents.

Be sure to check for Direct Relay Combinations. In some cases, the message can be delivered to recipients that reside at the relay station even if the passwords fail for other relay recipients.

For information on how Relay Fax Requests are handled see the Advanced Fax Store and Forward section.

Manual and Automatic Redial

Description:

Upon reception of a busy signal, the IFAX machine will automatically redial a prescribed number of times at a prescribed interval. The automatic redial flowchart is shown in FIG. 103. If the IFAX fails to receive a fax tone from the destination x consecutive times, it will assume that this is not a fax phone number and will stop redialing.

This option will be settable for the entire system rather than on a per-user basis.

Each user will also have the ability to manually initiate a redial of a previously attempted job that is queued in the outbox or scanner.

Options:

Number of Retries specifies the number of attempts to make before aborting the transmission.

Redial Interval the number of minutes to wait in between attempts.

Procedure:

If a connection cannot be made, attempt to connect the Alternative Fax Number (if available). If the connection still fails, increment the redial count.

After each attempt, wait the number of minutes specified by the user in the Redial Interval. Random intervals of 10-50 seconds will be added on to this period to prevent glare situations.

When the redial count is equal to the Number of Retries, abort the operation and print an "Could not connect to recipient fax machine" Error Message.

Multi Access

Description:

The IFAX 10 is designed so that any activities that can be done at the same time without contending for the same hardware will be allowed. The set of simultaneous activities possible at any one time may be limited by system parameters, such as the available memory.

Multi Access also allows the system to continue to function even when a particular peripheral is not functional. For example, the system will continue to send and receive faxes (to the extent of available memory) even when the machine's printer is disabled (e.g., paper out, toner out, paper jam, door open, etc.).

Procedure:

There are basically four key components with regard to Multi Access: the User Interface, the Printer, the Scanner, and the Fax Modem. However, this section will also describe the Power On/Idle control flow, multi access handling of the Stop hardware key and multi user requirements of the Outbox. The power on and idle flowchart are shown in FIGS. 104 and 105.

The User Interface should be available at all times. Thus, all processes spawned by user commands work in the background, leaving the interface available to the user.

The remaining three components should be able to operate simultaneously. Thus, a given feature should be available if the components it needs are available. If they are not, the completion of the feature must be placed on hold.

Sometimes this will require that the User Interface display a dialog indicating that the operation is on hold. For example, if the user requests a copy while an incoming fax is being printed.

At Power On, the system should follow these steps:

Initialize All Devices. Report any errors that occur.

Perform Self Test. Report any problems that exist.

Check For Power Interruption. If the machine lost power during an important operation, issue a Power Interruption Report.

Initialize User Interface. If public user access is allowed, display the main menu. Otherwise, display the Sign In dialog.

Enter Idle Mode

During Idle Mode, the system should:

Check For Outgoing Transmissions every minute. Poll the Outbox every sixty seconds for outgoing faxes and redial operations.

Monitor Fax Load balancing every five minutes.

Check Night Timer (if included) every fifteen minutes to see if the printer engine should be turned off during certain hours.

Re-Initialize User Interface every fifteen minutes. Sign out the current user. If public user access is allowed, display the main menu. Otherwise, display the Sign In dialog.

Perform Quick Diagnostic Check every fifteen minutes. Report any problems that exist.

Check Automatic Reporting every fifteen minutes. Route reports if the automatic reporting interval has passed.

Multi Access complicates the handling of the Stop hardware key. Follow these steps whenever the Stop key is pressed:

Does Stop apply to the action the user is currently performing. For example, is the user copying a document? Are they recording a quick key sequence? If so, stop the user's current action.

Does Stop apply to a background task owned by the current user? For example, is a job currently being transmitted that was queued as Send From Memory? If so, display a dialog asking the user if they'd like to interrupt this task, cancel this task or continue working.

Does Stop apply to a background task owned by another user? For example, is a job currently being transmitted that was queued by another private user? If so, display a dialog that says "You do not have authorization to interrupt this transmission."

Multi Access also complicates the functionality of the Outbox. IFAX platforms support an Inbox/Outbox messaging model. All immediate outgoing, scheduled outgoing, poll store, persistent poll retrieve and relay messages are stored in the system Outbox until they are ready for transmission (in the case of immediate outgoing messages, this is usually a very brief time period). They are removed from the Outbox once the messages have been successfully delivered or redialed to failure.

The System Outbox can be filtered in four different ways:

Private Outbox filter is used once someone signs in. The Outbox only shows messages owned by the current signed in user and publicly available messages.

Public Outbox filter is used when no one is signed in. The Outbox shows all publicly available outgoing messages.

Relay Outbox filter shows messages from other machines that are being stored and forwarded.

Administrator Outbox shows and provides access to all messages in the System Outbox when a user with administrative privileges signs in.

Immediate Scan

Description:

In order to reduce the time required to send a fax, the IFAX machine can begin scanning the document into memory immediately after the start button has been depressed.

When this feature is disabled, the system will wait until it attempts to connect with the recipient before beginning to scan.

Options:

Send From Memory turns off immediate scan. Each fax is scanned completely into memory before being transmitted.

Broadcast Fax automatically turns off immediate scan. Send From Memory is always used for broadcasts.

Full G3 Compatibility

Description:

The system will offer full backward compatibility with the existing worldwide G3 Fax Network.

Options:

Error Correction Mode (ECM) for highly accurate image and data transmission.

Page Retransmission Mode for re-transmission of corrupted pages.

1D and 2D Data Compression and Encoding Modes, including Modified Huffman (MH), Modified Read (MR), and Modified Modified Read (MMR) fax data encoding and decoding.

Voice Request on machines that support this feature.

Image reduction to accommodate different send and receive paper sizes.

8 minute close (for the German market)

Copy Document

Description:

The user will be able to make copies of documents by inserting the document in the IFAX document feeder and pressing the copy button. The copy document setup flowchart is shown in FIG. 106. The copy document control flowchart is shown in FIG. 107.

Options:

One Step Copy automatically makes one copy at the currently selected resolution when the user touches the Copy button. When this option is off, an additional dialog lets the user set these other options below:

Number of copies, supported on machines with sufficient memory.

Resolution, Contrast and Halftoning See the High Resolution Scan, Print, Send & Receive section for details.

Image enhancement removes stray pixels from scanned copy images.

Reduction/enlargement provided for certain paper sizes.

Procedure:

If One Step Copy is on, begin the copy operation with Number of Copies=1 and use the currently set Resolution, Contrast and Halftoning modes. Otherwise, begin the copy operation when the user presses Start (following the Copy settings dialog box).

If there is no document in the feeder, display a "Please Insert Document" dialog box. Continue when a document is inserted.

Scan and copy the document according to the settings (either from the Copy settings dialog or the One Step Copy instructions).

If Number of Copies is greater than one, collate the copies. In other words, while making the first copy, store the entire document in memory to make the remaining copies.

If Image Enhancement is on, follow the steps described in the Image Enhancement For G3 section.

Exceptions:

    ______________________________________     Document Cover Open                 Display a "Close Document Cover" dialog box.     Memory Full Display a "Memory Full. Can only make one                 copy" dialog box. i.e. There is not enough                 memory to collate multiple copies.     Paper Jam   Display a "Paper Jam" dialog box.     Paper Out   Display a "Paper Out" dialog box.     Power Off   At next Power On, clear the paper feeder.     Stop        Abort the operation. Clear the paper feeder.     ______________________________________

Programmable Function Keys (Autokeys)

Description:

The user will be able to record software macros for single step execution from the top level menu. The Autokey recording flowchart is shown in FIG. 108. Entire send or broadcast sequences can be easily recorded and repeated at the touch of a button.

Options:

Start beans execution of selected Autokeys.

Record allows the user to record a new Quick Key macro.

Remove removes a Quick Key sequence.

Procedure:

Quick Key sequences should be executed as if the user was pressing each button. This should be a simple procedure. If the user presses Stop during a Quick Key sequence, display a dialog "End Quick Key sequence x?"

Recording Quick Key sequences is a bit more complicated. When in Record mode, the status indicator of each screen and dialog should show "RECORD". When the user presses Start or Stop, terminate the record sequence.

Ask the user if the sequence just recorded should be set for public access. If not, this is a private key sequence (visible only when the current user is signed on).

Advanced Document Transmission

High Quality Renderable Document Transmission

Description:

The user will be able to send a renderable document, one that can be printed on IFAX machines and EFAX PCs with high quality. When this option has been specified and the IFAX is communicating with a G3 fax machine, the IFAX will render the document into G3 format using the highest resolution supported by the receiving fax machine.

Procedure:

This feature refers to the ability of an EFAX PC to render a document for transmission from an IFAX connected via LAN/Serial interface. The IFAX can transmit and render the Jumbo data to other fax machines, including G3 and IFAX.

Editable Document Transmission

Description:

The user will be able to send a native format document (binary file) to the recipient. The IFAX will send such documents without regard to their contents. If the IFAX encounters a G3 fax machine, it will abort transmission and inform the sender of the failure and reason.

The user can also choose to send both a renderable and editable version of a document, if they so desire.

Procedure:

The IFAX can transmit Editable documents as binary Attachments. The IFAX will send such documents without regard to their contents. Only EFAX aware recipients will be able to receive the binary attachment.

Each binary attachment should be counted as a single page at the end of the document. The Fax Viewer and the Mailbox will allow users to transfer these binary attachments to their PC's using the Mailbox Feature Save to Floppy.

Exceptions:

If the IFAX encounters a G3 fax machine, render a short message stating that a binary attachment could not be transmitted.

Support for Different Message Types

Description:

The IFAX machine and EFAX protocol will be designed to support the sending and receiving of documents that consist of multiple parts, each of which may contain different media types.

Some messages will contain binary Attachments of different types. Other messages will contain Phonebook information, Custom Cover Sheets. Configuration Settings, etc.

Some of these message types will be automatically recognized and acted on by the system while others will require the user to extract elements from each of these message types. Most of these message types will have to be defined in the Remote Access section.

Digital Cover Sheets

Description:

IFAX platforms can automatically generate digital cover sheets with custom styles and fax header information.

In communications between two IFAX 10 machines of the same construction, the cover sheet will be generated at the recipient's machine from message header information and the style template, contained as a message part. This will save transmission costs. However, when transmitting to G3 fax machines, the IFAX machine will render the cover page to a G3 format for transmission.

Unless the system also supports the Multiple Digital Cover Sheet Administration feature, the machine will probably ship with only one default Cover Style.

Options:

Customized Style defined by a cover page template editor. This style will affect the layout of the cover page and the remaining options.

Recipient List includes recipient names, fax numbers, phone numbers, (different cover styles display the list differently), To:'s and Cc:'s.

Personal or Corporate Logo, not supported on low end fax machines, the cover page template can include a small corporate logo on each cover page

Time and Date displays the time and date of the transmission.

Number of Pages displays the number of pages transmitted and (if known) the number of pages the user specified.

Procedure:

If the Include Digital Cover Page option is on, insert a digital cover page as the first page of the document. If you are communicating with an intelligent machine, transmit the cover template, otherwise (if G3), render the template to the current resolution.

It can include the following dynamic fields from the transmission:

Sender's Name, Company name and Address, Phone Number and Fax Number

Sender's cover page bitmap or default IFAX Logo

Recipient List with To:/Cc: designations

Time and Date

Number of Pages

List of Binary Attachments/Enclosures as "Encl:"

Cover sheets will be created with a Windows Cover Page Template Editor Applet. The editor will support dragging and dropping of text, picture objects and dynamic fields onto a blank cover sheet.

Text can be any caption in a user selectable font & style placed anywhere on the page. Picture objects are any OLE compatible bitmap format that can also be placed anywhere on the page. And finally, Dynamic Fields are like those listed above: Name, Company, Recipient List, Time and Date. Number of Pages etc. The dynamic fields are filled in differently for each transmission whereas the other objects are static. Note: custom fonts man be substituted by default font styles on other IFAX Machines.

Multiple Digital Cover Sheet Administration

Description:

The IFAX 10 supports a library of cover sheet styles. Each can be used for different tasks, formal, informal, confidential, personal, corporate, etc. Once created on a Windows Cover Page Template Editor, Cover Sheets can be downloaded to IFAX machines, transmitted to other intelligent platforms. etc. Each user can maintain a private library of cover sheets in addition to the publicly available cover sheets on their system.

When a user sends a message, they will be presented the option of including a cover page. If the select "yes." they can accept the default cover page specified during the user setup process or select an special purpose cover page.

Options:

Install adds cover sheet styles to the public or private library on a given IFAX Machine.

Remove deletes cover sheet styles from an IFAX Machine.

Enclose allows users to send .CPX files to other users so that they can share and exchange cover sheet styles.

Print allows users to print a copy of the cover page template before using.

Preview allows users to see the cover page template on the LCD display before using or printing.

Procedure:

IFAX platforms support the storage of Multiple Digital Cover Sheets. Users can add or remove cover sheets to a private or public library of system cover styles. The cover page installation flowchart is shown in FIG. 109.

When new cover styles are installed, display a "Allow public access?" dialog. If the user presses no, then the cover style should be added to the user's private list instead of the public list.

Automatic Relay Fax Request

Description:

The system will optionally support automated routing of faxes via selectable relay points. Administrators can establish that either all messages should be routed via a relay point or that messages with particular area codes or country codes should be relayed.

If the relay is unsuccessful, the system can be configured to either retry the relay point at a later time or attempt to send the message directly.

For more information, see the Relay Fax Request feature description.

Options:

Default Relay Point specifies that all outgoing transmissions should be sent through this relay point.

Relay by Prefix specifies that outgoing transmissions should be routed through various relay points according to their prefix.

Send Directly After Failure specifies that the machine should try to send the message itself if the relay connection fails.

Procedure:

The automatic relay flowchart is shown in FIG. 110. With each outgoing transmission, compare the prefix to those in the Automatic Fax Relay Request List. If they match, automatically re-route the transmission through the relay point.

If a Default Relay Point is specified, route all transmissions through this relay point. Note: Relay By Prefix settings have preference over the default.

If any of the relay connections fail and Send Directly After Failure is specified, transmit the document directly to the destination.

See the Relay Fax Request section for more information.

Advanced Fax Store and Forward

Description:

The system will be able to accept relay requests described in the Relay Fax Request and Automatic Relay Request features. Forwarding requests can be of the following types:

Direct Relay Combinations allow users to specify recipients that reside on this relay point in combination with other relay recipients that reside at different fax numbers.

Multiple Relay Recipients can be specified so that this relay point will actually perform a Broadcast operation.

Nested Relay Recipients can be included so that this relay point will send a broadcast list to another relay point, and so on. This enables advanced document distribution over complex corporate networks.

Discount Rate Relays control the time and costs of the relay point transfer. This option specifies the relay execution should wait until the discount rate period begins.

Procedure:

The IFAX 10 can operate as a Relay Station to provide Advanced Fax Store and Forward capabilities. The Relay Station accepts incoming Fax Relay Requests and then forwards them to the designated recipient(s). The advanced store and forward flowchart is shown in FIG. 111.

When the Relay Station receives the Relay Fax Request, it must first verify the caller's relay access rights. Compare the Relay Password to the relay station's System Password. If they don't match, compare both system's System Password. If they don't match, issue an error report.

Be sure to check for Direct Relay Combinations. In some cases, the message can be delivered to recipients that reside at the relay station even if the passwords fail for other relay recipients.

If either of the passwords match, accept the relay message and store it in the Outbox. If Discount Rate Relay, is specified, store the message in the Outbox until the start of the discount rate period.

As soon as the phone line is available, begin broadcasting the message to members of the Relay List. Since this operates as a normal Broadcast operation originating from the Relay Station, all of the Broadcast procedures should be used including Intelligent Fax Queuing, Automatic Relay Fax Request and Fax Load Balancing checks.

If the original sender requested a Confirmation Report, print a Confirmation Report when the Relay Station accepts the fax. Once the Relay Station delivers all the messages, send back a Relay Confirmation Report to the original Sender (using the return relay address, still an open issue).

Relay Stations can also be Polled for the transmission status of Relay Messages. See the Check Relay Status section of the Polled Fax Retrieve feature.

For more information on Fax Relay Requests, see the Fax Relay Request section.

Exceptions:

    ______________________________________     Password Invalid                 If neither the Relay Password or the System                 Passwords match, return an Error Report to the                 Sender stating that they have no Relay Access on                 this Relay Station.     Relay Delivery Failure                 If the Relay Station cannot successfully relay the                 message to its destination(s), send back a Relay                 Failure Report to the original Sender.     ______________________________________

Intelligent Fax Queuing and Multicasting

Description:

IFAX platforms will automatically consolidate faxes headed to the same destination into one fax transmission. This will send multiple messages in a single call, saving connection charges.

When a single fax is sent to multiple recipients associated with a single destination IFAX machine, that fax will be sent only once and distributed to each user by the destination IFAX machine (only supported during transmissions between two IFAX 10 of the same construction).

Procedure:

The intelligent facsimile queuing and multicasting flowchart is shown in FIG. 112. Whenever a fax number is about to be dialed, the system Outbox should be checked for other faxes waiting to go to the same destination,this includes recipients at a common fax number on the initial message.

Transmissions scheduled for discount rates should never be consolidated with transmissions made during peak hours.

We should be careful about consolidating Secure faxes without maintaining the same high level of security.

Separate Confirmation Reports should still be generated for each consolidated fax message.

Fax Load Balancing

Description:

IFAX platforms will automatically monitor system loads and reallocate jobs across a Local Area Network when necessary. When a machine becomes heavily loaded, it will send a message to other machines looking for assistance. When another available machine responds, the IFAX machine will transfer outgoing fax messages to this available machine via a simple relay request.

Procedure:

The load balancing flowchart is shown in FIG. 113. When there are more than five outgoing faxes (scheduled for as soon as possible) waiting in the Outbox, send out a request for assistance over the LAN to each of the IFAX Machines in the Load Balancing configuration list. This list must be set up in advance by a user or system administrator. Each machine must have identical system passwords.

If the requesting IFAX is listed in the other IFAX Machines' Fax Load Balancing List, they will respond with a Load Factor message. This shows the number of messages on their queue.

The requesting IFAX can then distribute the overloaded messages via LAN to the other IFAX Machines. An IFAX Machine should use caution not to overload another IFAX Machine's queue more than its own. The number of messages distributed should not force the destination machine's Load Factor over five messages.

The request is called a Load Balance Transfer Request. If the machine accepts the Transfer Request, it will send a confirmation to the original machine. If the confirmation message is not received within ten minutes, assume that the transfer request failed (was denied). This should assure that messages do not get lost while between two machines. Therefore, don't delete the message from the Outbox until the Transfer Request confirmation has been received.

Once the messages have been transferred to the other IFAX Machines, they behave just like Relay Fax Requests. So status and confirmation work similarly to the Advanced Fax Store and Forward section.

IFAX Machines cannot make Transfer Requests on messages that they have accepted from other IFAX Machines. This should prevent a glare situation on the network.

Alternatively, the IFAX 10 could make a Load Balance Transfer Request based on the size of the outgoing facsimile messages or the time required to transmit the outgoing facsimile messages.

Exceptions:

    ______________________________________     Network IFAX No                  If the requesting IFAX Machine is not listed     Permission   in the Nerwork IFAX's Fax Load Balancing                  List, permission will be denied.                  An Error Report should be sent to the System                  Administrator.     Network IFAX Not                  The IFAX Machine in the Fax Load Balancing     Found        List was not found on the network. Send an                  Error Report to the System Administrator.                  Put the original message back in the IFAX                  Machine's own queue.     Transfer Request Denied                  If the destination Load Balancing machine                  denies the transfer request, attempt to transfer                  jobs to other machines.     ______________________________________

Fax Stacking

Description:

When the IFAX machine's document feeder contains a fax message that is either being scanned or waiting to be scanned, the user will be able to "stack" another fax on top of the currently loaded sheets. The first page of a stacked message must be an OMR-coded IFAX cover sheet, from which the system will determine the message's sender and recipient.

Procedure:

When scanning the top of each page, check for the OMR mark at the top left of the page. If the mark is found, the previous job should be completed and the OMR job started next.

Exceptions:

    ______________________________________     Missing Information                 If the OMR Engine cannot locate parts of the                 data, the fax should be fed through until another                 OMR Cover Page is found. An Error Message                 should be printed after the fax is                 fed through indicating that it was not sent.     Paper Stuck If the last page of one fax feeds in with the                 OMR Cover Page of the next fax we might                 accidentally transfer documents to an incorrect                 destination.     ______________________________________

Alternative Number Calling

Description:

The user may specify an alternative number to send a fax to if the first number is busy or other-wise unavailable. The alternative fax number is part of the standard intelligent fax address type.

Procedure:

If a Send, Broadcast, Poll Retrieve or Relay Fax Request is unable to connect to a remote machine (No Carrier), it should try the Alternative Fax Number entry of the Recipient Address (if available) before incrementing the Redial count.

Each subsequent retry should try both the standard fax number and the alternative fax number in that order. For more details, see the Manual and Automatic Redial feature description.

Fax Outbox Management

Description:

The user will be able to view a list of all messages queued for transmission and perform the following actions:

View Messages allows users to use the previewer to look at outgoing messages and see the status of the transmission.

Print Messages prints copies of outgoing messages.

Cancel A Fax aborts outgoing fax messages and cancels persistent poll retrievals.

Edit A Fax allows users to change the recipient list and fax settings of outgoing transmissions.

Manual Redial specifies immediate redial of outgoing messages.

Sort orders outgoing faxes by recipient or status.

Received Fax Preview

Description:

The system will support viewing fax messages held in the user's mailbox. Users will be able to select from several viewing modes, including fall page, and actual size. The quality of viewing in these modes will depend upon the resolution of the IFAX machine's screen and the fax message.

Options:

View Messages allows users to look at received faxes, zooming in or out on specific areas and providing special handling of binary attachments.

Print Messages prints copies of received faxes.

Delete removes messages from the Mailbox.

Save copies the message and attachments to a peripheral drive (e.g. floppy)

Forward lets users send messages on to other recipients.

Sort orders received faxes by sender or status.

Remote Access

Description:

Users will be able to control features of their IFAX 10 from remote locations using Windows PC's connected via serial or through any PSTN interface using an IFAX or EFAX PC.

Options:

Fax From Windows allows users to send, receive, broadcast, poll, etc. from a Windows platform using an IFAX Machine as a gateway.

Remote Printing From Windows allows users to print documents from Windows using the IFAX Machine.

Remote Scanning From Windows allows users to scan documents to their PC using the IFAX Machine.

Remote Mailbox Control allows users to browse their mailbox, view, print and retrieve files remotely.

User Administration allows users to setup the preferences from a remote location. Users will be able to access all features described in the User Administration feature description previously described in connection with FIG. 61.

System Administration allows administrators to configure and monitor a single IFAX 10 or entire network of IFAX Machines from a Windows PC. System administrators will be able to access all features described in the System Administration feature description.

The system will support such remote connections via all available and appropriate external interfaces e.g., PSTN, LAN, and serial connections (including those with attached external data modems--this connection method is considered low priority for the first release).

Voice Playback and Record Support

Description:

The IFAX 10 will provide the ability to install voice playback and recording hardware, as would be used in a fax-on-demand application. The hardware vendor will be responsible for developing the system driver to support this functionality and the application that uses this functionality. The IFAX software will provide system level support, which includes storing and accessing sound files and delivering these files to the sound device driver.

The installation of such systems can have potentially significant impact on system hardware requirements. These include additional system memory, hardware to decompress and play sound files, hardware to receive microphone input and convert it to sampled, compressed sound files, and the ability to distinguish between voice and fax incoming calls.

Secure Transmission and Reception

Document Encryption

Description:

The system will allow users to encrypt fax transmissions to guard against reception of readable documents by unintended recipients.

Procedure:

If the Encryption option is on, the contents of the document is encrypted with the public key of the Recipient(s). The encryption process must be done separately for each Recipient.

If the Recipient's Public key is stored with their address, the encryption can be done before the call is initiated. Otherwise, the encryption may have to occur on the fly once the key has been obtained.

The Public Key should be stored for later use with the Recipient's Address.

Document Authentication

Description:

The IFAX 10 has the ability to verify the identity of the sender and recipient before transmitting the fax message.

Procedure:

If the Authentication option is on, the document should be encrypted with the private key of the sender and attached to the sender's Digital Certificate.

The Digital Certificate is a copy of the sender's Public Key encrypted with the Private Key of the IFAX Security Authority.

The Recipient can then verity the identity of the Sender by decrypting the Digital Certificate with the Public key of the IFAX Security Authority and using it to decrypt the document.

The Authentication process can occur before the call is made since all the necessary keys should be available.

Digital Signature

Description:

The system will have the ability to include a checksum (or conceptual equivalent) to verify that the received document contents are the same as those sent by the sender.

Procedure:

If the Digital Signature option is on, the document should be processed through an IFAX hashing algorithm. The resulting hash code should be encrypted with the Public Key of the Recipient(s).

The receiving IFAX Machines run the document through the IFAX Hashing algorithm as well and compare their hash code result to the hash code they decrypt with their private key.

If the hash codes are identical, the document has not been tampered with.

The Hashing can be done before the call is made but the encryption of the hash code must be done when the Recipients' Public Keys are available (possibly before the call).

Send, Receive, and Relay Access Restriction

Description:

This feature allows users to place restrictions on the external fax machines that can communicate with their fax machine.

Options:

Restrict Transmission To Phonebook List prevents users from sending to members outside the phonebook. This can prevent mis-dialing as well as unwanted long distance calling. Of course, users can override this by adding members to the phonebook.

Restrict Reception By Phonebook List prevents junk fax by restricting accepted faxes from members of the phonebook.

Restrict Reception By System Password restricts reception of faxes to machines that have the same system password, usually a small closed network of machines.

Remote Procedure Calls Allowed turns on/off remote access to the fax machine.

Relay Passwords prevent outside callers from using fax relay features without specifying a specific password.

User Access Restriction

Description:

Users and administrators can create password-protected personal mailboxes for receiving and storing faxes. IFAX platforms also support personalization of user account settings and preferences. Users can access these personal mailboxes and settings by signing in to the IFAX Machine.

Options:

Sign In personalizes the system according to the user's preferences and provides them access to their personal mailbox.

Sign Out returns the system to its default mode, restricting access to secure mailboxes.

Public Access allows the system to be used without signing in. Public access provides the same functionality as personalized access without the security.

Procedure:

The sign in flowchart is shown in FIG. 114. At Sign In, request a password to verify the user's identity. If the password is correct, check to see if the user has any new unread messages. If so, display the "You have x unread messages" dialog.

Switch the main menu Mailbox status indicators so that they indicate the status of the personal Mailbox. Adhere to personal preferences specified in the User Level Administration section.

If the system has been idle for fifteen minutes, automatically sign out any logged-in user. The sign out flowchart is shown in FIG. 115.

PC Connectivity

Automatic Inbound Routing

Description:

The IFAX 10 support automatic routine of incoming messages. When a fax message is received from another IFAX machine or a G3 message is received that includes an OMR cover sheet, that message will be routed to the destination specified by the recipient.

Options:

Print Received Faxes specifies that incoming faxes should be printed.

Store In Mailbox specifies that incoming faxes should be stored in the recipient's own mailbox.

Forward To PC actually routes the faxes directly to the recipients PC via LAN or Serial.

Forward To Tool Application routes the fax to a specific Tool Application for special handling.

Support for Automated G3 Inbound Routing Software

Description:

The IFAX 10 can support different methods for inbound routing of G3 faxes.

Options:

Optical Mark Recognition (OMR) determines recipient's from marks on a special cover page.

Optical Character Recognition (OCR) converts cover page to text and searches for the recipient's name.

Direct Inward Dial (DID) provides each fax user a unique fax phone number. Many such phone numbers are mapped by the telephone company's switch onto a physical telephone line. When an incoming call is answered, the central office sends touch tones that represent the number being called.

Dual Tone Multifrequency (DTMF) prompts the sender to enter touch tone digits to identify the fax recipient when a fax call is answered.

G3 Sub-addressing Field supports future extensions of G3 that identify recipients.

Route To Special Mailbox specifies that G3 and unknown faxes should just be routed to a particular mailbox where they will be handled manually.

Procedure:

If Route To Special Mailbox is selected, the all unknown faxes should be routed to the specified mailbox.

Otherwise, unknown faxes should be routed to the specified Toolbox Application. The Application will then handle the routing as above.

Automatic G3 OMR Cover Sheet Recognition

Description:

The system will automatically scan received G3 messages and detect whether the first page is an IFAX-compatible OMR cover sheet. If so, it will do the following:

1. Read the OMR-coded information (including at least the sender and recipient name)

2. Determine whether the recipient is a valid IFAX user.

3. If so, route it in the manner designated by that user for all incoming messages. The sender's name decoded from the OMR marks will be displayed in the incoming fax log.

4. If the decoded recipient is not a valid user or the system is unable to decode the recipient from the cover page, the message will be routed to a mailbox designated for such messages by the system administrator.

Procedure:

Scan the upper left corner and look for an OMR identifying symbol. If the symbol is not present, this is not an OMR cover page.

Scan the OMR bar code and determine what kind of form this is. Scan the fields and form appropriately and return the information to the calling application.

Local and Remote Administration

User Level Administration

Description:

IFAX platforms will let individual users personalize their system and maintain a secure mailbox for storing messages. Because IFAX platforms are consumer devices, we do not assume that an administrator is necessary. Therefore, individual users can also change system settings listed in the System Administration section.

Options:

Create/Edit Personal Mailbox allows the user to set up a secure personal mailbox for receiving and storing fax messages. Also lets the user fill in their EFAX Address information.

Security Keys allows the user to obtain, add and remove their RSA IFAX Public Security Keys.

Handling of Incoming Faxes allows the user to select from among the routine options described in the Receive Fax feature description.

Preferred Initial Screen allows the user to select a default initial screen.

Cover Page Styles allows the user to modify the public and private Cover Style library.

Phonebook allows the user to modify the public and private phonebook list.

Procedure:

If a user Creates A Personal Mailbox, create a mailbox file for them on the hard disk. Add their name and password to the accounts list. Also, add their name and address to the public phonebook.

In Security Keys, if the user chooses to change their public key, dial the Key Authority and issue a change key request. Delete the old key and store the new key. If the user chooses to print the key, render a fat bits image of the 512 bit key. Ask the user if they want to remove the key from the system so they are holding the a secure paper copy. If so, delete the key from the system. They can always re-install the key by scanning the paper copy. Use OMR to scan fat bit security keys into memory.

The Preferred Initial Screen should be displayed at Power On, after a transmission operation has been successfully Started (by user pressing Start), or after fifteen minutes of idle time.

When the user asks to install Cover Page Styles, search the mailbox and peripheral drives for cover page files or attachments. For each one, ask the user if they want to install it and whether it should be public or private access. If they do install it, add it to the Cover Page Style list.

For comments on Incoming Fax Handling, see the Receive Fax section. For comments on Phonebook, see the Phonebook Maintenance section.

Exceptions:

    ______________________________________     Duplicate Mailbox Name                  If a user tries to create a mailbox with a name                  that already exists, display a "Duplicate                  Mailbox Name" dialog and force them to                  change the name somewhat so that there is                  not an exact match.     ______________________________________

System Administration

Description:

IFAX platforms support changing of System settings and other Administration functions by individual users or administrators. Because IFAX platforms are consumer devices, we do not assume that an administrator is necessary. Therefore, at first, individual users can change most of these feature settings. Later, experienced users can add higher levels of security very easily.

Options:

IFAX Identification Information allows the changing of TTI, RTI and CSI-equivalent fields.

Time and Date sets the system clock.

Discount Rate Period sets the starting time for discount rates or lets the IFAX Machine determine this automatically.

Automatic Redial sets the number of retries and redial interval.

Phone Line Settings sets the dial mode (pulse/tone) and other settings.

Mailbox Accounts lets administrators configure and remove mailbox accounts.

Administration Mode turns on more of the security features.

Administration mode can limit system settings to particular users.

Touch Screen Calibration allows setup and re-calibration of the touch screen display.

Access Restriction sets the transmission and reception restrictions.

Automated Store and Forwarding sets default relay stations.

Automated Activity Reporting sets the frequency and destination of automated activity reports.

Automated G3 Routing sets the handling for G3 and unknown faxes.

Fax Load Balancing sets the network for Fax Load Balancing.

Fax Overflow sets the handling of fax overflow situations.

Remote Trouble Notification sets the user and location for remote trouble reporting.

Procedure:

The Administration Mode dialog is the most important since it allows administrators to restrict access of some system activities. In order to access this feature, users must present the system access code or already have administrative privileges.

Phonebook Maintenance

Description:

The phonebook 62 (see FIG. 62) allows users to quickly send to commonly used fax destinations. Phonebook entries are entered by the users directly or automatically during send and receive operations.

Options:

Public/Private entries are separated in the address book so that each user can have his own private list.

Group Addresses are supported so that users can pre-program commonly used broadcast lists.

Relay Addresses are supported for simplifying complex fax network transmission.

Procedure:

Each Phonebook has three types of entries: Single Recipient entries. Group entries, and Relay Station entries.

Single Recipient entries consist of the following:

Name

Fax Number

Alternative Fax Number

Voice number

Company Name/Comment

Street Address

Technical Protocol Parameters

Group entries consist of:

Group Name

Member List of Phonebook entries (Single Entry, Group, or Relay Station)

Relay Stations consist of:

When users change a phonebook entry, check all outgoing faxes to see if they are affected. Before changing the entry, ask the user if the outgoing fax addresses should be updated.

Exceptions:

    ______________________________________     Duplicate Address                 If a duplicate address is entered, display a dialog                 to the user. Do not create a copy.     Duplicate Name                 If just the Name is duplicated, display a dialog                 to alert the user that there is a name entry with                 multiple fax numbers.     Phonebook Corrupted                 If the Phonebook is corrupted, incomplete entries                 should be printed in the Error Report and                 then erased.     Phonebook Full                 If the Phonebook becomes full, a dialog should                 alert the user that no more entries can be added.                 No additional EFAX Addresses from Received                 Faxes should be added to the Phonebook.     ______________________________________

Fax Overflow

Description:

The IFAX 10 allows users or administrators to designate how the system should respond when there is insufficient storage space to receive and store another fax message.

Options:

Alert User/Administrator will send a message to this person that the fax is in overflow mode.

Don't Answer will prevent other faxes from coming in.

Route To PC presents messages to a PC attached to the IFAX via Serial/LAN

The system will also display a "Fax Overflow" dialog box on the LCD indicating that the fax can no longer receive messages due to the overflow condition.

Procedure:

If a fax overflow condition occurs, display a "Fax Overflow" dialog box. Redisplay the dialog every fifteen minutes as necessary. Notify the user specified about the overflow condition.

If Don't Answer is specified, don't answer the phone if it rings. Otherwise, route incoming messages to a PC attached via Serial/LAN (running special IFAX software).
